Pre-Installation Instructions
1.
This product must be installed according to all applicable
building and life safety codes.
2.
Due to the variety of mounting configurations available with
this product, a survey and assessment of the physical area
in which the product will be installed must be performed.
3.
The door frame must be inspected and deemed structurally
sound prior to installation of the electromagnetic lock. The
structural integrity of the mounting surfaces must be strong
enough to meet or exceed the holding force of the product.
4.
The product must be protected from potential damage due
to intruders or tampering.
5.
The product should be installed in a location that will not
hinder or create a potential safety hazard to authorized
personnel accessing the protected area.
6.
Because electromagnetic locks are used in a variety of
applications and different door frame configurations, an
experienced installer with knowledge of this product must
make a determination of the optimal mounting method for
this specific application.
7.
The components, hardware, installation instructions and
mounting template included with this product are intended
for use on outswinging doors.
8.
Do not install this product on the exterior of buildings.
9.
Do not use as a doorstop. This will void warranty.
10.
Installation of this product should be done by an
experienced installer with knowledge of this product.
NOTE:
It is highly recommended that thread locking compound
be applied to all screws during installation to reduce chance of
screws loosening over extended time.
NOTE:
New Installation:
Retrofit Installation:
During the installation of the armature plate to the door it
is essential that the armature plate remains movable. The
armature plate must be allowed to pivot on the center-mounting
bolt to allow proper alignment with the magnet surface. If the plate
is not aligned with the magnet surface, the lock may lose holding
force or not lock at all.
The head of the armature mounting bolt ships with a rubber washer
affixed to it. This washer should project slightly beyond the surface
of the armature plate. This is to allow the washer to expand when
power is removed and break the air vacuum between the plate and
magnet surface. If this washer is removed or trimmed, the lock will
appear to have some holding force even when power is removed.
PLEASE DELIVER ALL INSTALLATION INSTRUCTIONS TO
THE END-USER UPON COMPLETION OF THE INSTALLATION.

Do not use as a doorstop. This will void warranty.
Step 1c)
Mount Armature Plate
Position bolt with rubber head through the armature plate.
Carefully apply thread locking compound to exposed thread.
Secure armature plate to door and armature holder by
threading
into
sexnut.
Step 1d)
Mount Electromagnetic Lock
Remove blocking screws from front of lock.
Remove electromagnetic lock from mounting bracket by
loosening captive screws and sliding off keyholes.
Attach bracket to header with the 2 panhead machine screws
or the self drilling screws provided through the slots.
NOTE: Do not over tighten these screws as the bracket may
need adjustment.
Slide electromagnetic lock onto mounting bracket keyholes.
Engage 1 captive screw at each end through bottom to fix lock
position on bracket.
Adjust alignment to ensure full contact of magnet with
armature plate.
Carefully remove electromagnetic lock without shifting
mounting bracket.
Secure mounting bracket in position with either 9 TEK™
screws or 4 flat counter sunk machine screws.
Drill ¾ (19mm) wire access hole using mounting bracket as
a guide. Tip the electromagnetic lock to expose the 4 captive
mounting screws. Carefully apply thread locking compound to
exposed threads. Slide the electromagnetic lock onto
mounting bracket keyholes.
Secure with 4 captive mounting screws.
Attach bracket to header with 9 TEK (tm) screws or 4 flat
